thingsSDK's Flasher.js project needs a manifest repository. I'm in the process of writing an expressjs-backed react/redux app that lets users store, edit and delete documents used for flashing microcontrollers. Once the manifests are approved by administrators, they can be published. This is a work in progress, but you can view the current state of the repos linked below.

A list of 700 - 1,000 books needed to be built daily in a specific order from another list.

Manually building this list took an employee 30-45 minutes each day in Excel.

I wrote a script to scrape the source list (HTML webpage), reorder and paginate the items at the click of a button. The results could them be printed directly from the browser. The lists are styled to exactly match the appearance of the excel print-outs they replace. Here's a link to a demo, click the button in the upper right corner to run it.

Some features of this solution:

Regular expressions match call numbers and sort each book title to the correct list, in the correct order.

Reporting of stats, including list of unmatched, for regular expression tuning or adjustments of source records.

Additional lists can be combined with the current list, a process that will remove duplicates.

The interface also accepts new lists (HTML) to transform, replacing the current content.

A client needed an engaging construction page while he designed his website. I created a "peephole" with jQuery and JavaScript that visitors can move around with the mouse to look at the painting behind.

This was just an evening's adventure to see how hard/interesting it might be to build a world with js and css sprites.
My friend had a few sprite sheets he created for a video game that never materialized. I thought it would be fun to animate the loch-ness monster.
